删除章节标题页上的灰色章节编号框

Question

我已成功在每页的边缘添加了一个灰色框（经过小幅修改），并标明了章节编号，代码如下“在每个页边距上显示当前章节号”。我试图从每章的第一页删除章节号框，例如，如“在每个页边距上显示当前章节号的编辑框”。

但是，在后一篇文章中，我找不到负责删除“第一页章节”框的代码片段。如果尝试添加\makeatletter和\makeatother部分，但输出没有变化。也\cleartooddpage[\thispagestyle{empty}]不起作用。

您可以在下面找到我的代码。有什么建议吗？

以下建议基于 KOMA-Script 书（德语）附录中的示例：

\documentclass[10pt,twoside,parskip=half]{scrbook} % Document class for PhD manuscript
\linespread{1.1}
\usepackage[
   paperwidth=170mm,

   inner=30mm, outer=25mm,
   heightrounded=true
]{geometry}

\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{scrlayer-scrpage}

% the following bases on an example in the KOMA-Script book:
